After a few hours of rambling finally I got a working node-visitor. Which recursively visits every required module starting from the definied entry point.
Behind the scenes using node-detective to find all require calls and Node core module to resolve filename. Maybe I will create a package in the future as it gets more mature. In the meantime I have created a simlpe gist demonstrating the core function. Enjoy! ;)
var fs = require('fs');
var path = require('path');
var Module = require('module');
var detective = require('detective');
// node-visitor
function visit(request, parent) {
var fn;
try {
fn = require.resolve(request);
} catch (err) {
fn = Module._resolveFilename(request, parent);
}
if (!path.existsSync(fn)) {
return;
}
console.log(fn);
var src = fs.readFileSync(fn);
var requires = detective(src);
requires.forEach(function(item) {
visit(item, {
id: request,
filename: fn
});
})
};
visit('../lib/application');
